Overview:

There are a large number of different types of flexible couplings available for use in the pump industry today. Each has its own features and benefits, but all are required to perform three primary functions: connect two shafts, transmit rotary power, and accommodate shaft misalignment. This document outlines pumping industry standard practices to select flexible couplings based on application requirements.  Along with basic selection techniques, this document will review the most common styles of couplings found on pump applications across different industries today. The document also provides the user with general guidance on the installation and maintenance requirements of each coupling type.  

Highlights:

• Provides a basic understanding of the various coupling types, information required to make basic coupling selections based on system requirements, and a general understanding of the installation and maintenance practices associated with each type of coupling styles found on pump applications across different industries today
• Basic features and benefits of each of these coupling styles discussed to help familiarize the user with the characteristics associated with each type
• Document outlines pumping industry standard practices to select flexible couplings based on application requirements
• Intended for those responsible for maintaining or selecting flexible couplings, including rotating machinery maintenance personnel and those responsible for designing or specifying pump systems
